Chapter 8 Ultra ATA Storage Driver Setup

8.1 Introduction

This driver takes advantage of the latest Intel ® Ultra ATA controller fea- tures to improve both storage subsystem performance and overall system performance. A useful diagnostic tool, Intel Ultra ATA Companion® , shows technical information of the ATA subsystem.

8.2Features

•The driver enables fast Ultra ATA transfers by default.

•Users no longer have to manually enable DMA transfers for each ATA and/or ATAPI peripheral devices.

•Each ATA channel has independent device timings/transfers which allows PIO-only and DMA-capable devices to share the same ATA controller cable, where one is the master and the other the slave, without restricting transfer mode to PIO-only for both devices.

•Technical details of the ATA subsystem can be viewed via use of the application.

•Drivers are optimized.
